World’s Thinnest Solar Charger is as Thin as a Paper

Known as the lightest and thinnest solar charger to date, the solar paper charger is only as thin as a stick of a gum.

Capable of charging big smartphones such as the Galaxy Note 4 and iPhone 6 plus, the solar paper charger is 1.5 mm thin, can fit between the pages of a notebook or planner, and weighs 120 grams.

Although solar chargers are abundant in the market, most of these chargers are either too heavy or too bulky making it inconvenient to be carried around. Moreover, some of these chargers take a very long time to charge the gadgets.

YOLK, the company behind the smart invention, created a small scale personal charger which will provide convenience to on-the-go-users . The solar paper charger can fully charge a gadget in just 2.5 hours in full sun. But you can also charge the device through partial or indoor sunlight and see if it’s getting enough power by checking its built-in-meter.


The charger comes with basic two panels which currently sells for $69. Although it can charge smartphones and other small devices, you may need to add a third or fourth panel to charge tablets and cameras. Each single unit of the device outputs around 2.5 watts. Users can configure this by adding extra panels in the multiples of 2.5 W such as 2.5 W, 5 W, 7.5 W and 10 These can be snapped together magnetically.

The new project is currently seeking funds on Kickstarter to commercialise the device. It has already received over $200,000 from backers so we can expect the new devices to appear in the market by September.

The Solar Paper charger can be used to charge a range of devices including smartphones, Bluetooth speaker, external battery, GoPro, Digital camera, flashlight, tablet, and double recharging battery charger.
